generateETA | R Documentation |
Generate individual random effects from a multivariate normal distribution.
generateETA(n, omegaLT, omega = LTmat(omegaLT), eta.names = colnames(omega))
n |
The number of individuals. |
omegaLT |
A numeric vector giving the elements of the lower triangle of the covariance matrix by row. |
omega |
The covariance matrix. |
eta.names |
A character vector of names for each random effect
(defaults to the column names of |
An n \times p
matrix, where each row contains the vector of random
effects for one individual (p
is the size of the covariance matrix).
